I got a nice comment on a blog post form Pamela Rawson and I ended up reading her neat post talking about her new 3D geometry class:
The point of the Week 3 MTBoS Blogging initiative isn’t the course specifics, I know, but still the idea of a 12 week course focusing on 3D geometry captured my imagination. I never studied 3d geometry in any formal way, but exploring that subject with my kids has been incredibly fun.
and more recently this tweet from Simon Gregg (and the animated gif inside of his blog post) inspired a super fun project:
My work prepping to explore folding a dodecahedron into a cube with the boys is here:
and the project with them is here:
Can you believe that a dodecahedron folds into a cube!
Moving away from our Zometool-related projects, we’ve done a few fun 3d geometry projects using just snap cubes. For example, this tweet from Five Triangles made for a neat project:
A neat counting problem shared by Five Triangles
This project explored the connection between the sum of squares – and geometry:
and it was realted to another 3D geometry project inspired by a tweet from James Key:
A neat geometry project inspired by a James Tanton / James Key tweet
I could go on and on and on and on, but I’ll just stop at one more fun one – the volume of a sphere:

All of our 3D geometry projects have the “3D Geometry” tag on the blog, that list of projects is here:
It is such a fun subject!!

Thanks, Mike. Those are really cool ideas!
